Description
用了readPreference参数无效果，看文档好像也没有相关参数。
如果我直接指定host为Secondary的地址，结果还是会走到primary上面执行

Research direction
Start at the mongodbreader entry point and inspect how the readPreference parameter and host are passed into the MongoDB connection. Reproduce the replica-set case described in the issue, then verify that a secondary-only preference routes reads to Secondary rather than Primary.
